Gmail’s web interface had a widespread outage earlier today, lasting about 100 minutes. We know how many people rely on Gmail for personal and professional communications, and we take it very seriously when there’s a problem with the service. Thus, right up front, I’d like to apologize to all of you — today’s outage was a Big Deal, and we’re treating it as such. We’ve already thoroughly investigated what happened, and we’re currently compiling a list of things we intend to fix or improve as a result of the investigation.

Here’s what happened: This morning (Pacific Time) we took a small fraction of Gmail’s servers offline to perform routine upgrades. This isn’t in itself a problem — we do this all the time, and Gmail’s web interface runs in many locations and just sends traffic to other locations when one is offline.

However, as we now know, we had slightly underestimated the load which some recent changes (ironically, some designed to improve service availability) placed on the request routers — servers which direct web queries to the appropriate Gmail server for response. At about 12:30 pm Pacific a few of the request routers became overloaded and in effect told the rest of the system “stop sending us traffic, we’re too slow!”. This transferred the load onto the remaining request routers, causing a few more of them to also become overloaded, and within minutes nearly all of the request routers were overloaded. As a result, people couldn’t access Gmail via the web interface because their requests couldn’t be routed to a Gmail server. IMAP/POP access and mail processing continued to work normally because these requests don’t use the same routers.

The Gmail engineering team was alerted to the failures within seconds (we take monitoring very seriously). After establishing that the core problem was insufficient available capacity, the team brought a LOT of additional request routers online (flexible capacity is one of the advantages of Google’s architecture), distributed the traffic across the request routers, and the Gmail web interface came back online.

What’s next: We’ve turned our full attention to helping ensure this kind of event doesn’t happen again. Some of the actions are straightforward and are already done — for example, increasing request router capacity well beyond peak demand to provide headroom. Some of the actions are more subtle — for example, we have concluded that request routers don’t have sufficient failure isolation (i.e. if there’s a problem in one datacenter, it shouldn’t affect servers in another datacenter) and do not degrade gracefully (e.g. if many request routers are overloaded simultaneously, they all should just get slower instead of refusing to accept traffic and shifting their load). We’ll be hard at work over the next few weeks implementing these and other Gmail reliability improvements — Gmail remains more than 99.9% available to all users, and we’re committed to keeping events like today’s notable for their rarity.

Sometimes you need to get your tasks out of Tasks. Although you already know how I feel about paper, we decided to add support for printing with Tasks’s graduation from Gmail Labs. Today we’re offering another export solution which doesn’t kill trees: emailing a task list.

Like most Tasks features, “Email task list” can be found in the Actions menu.

Clicking on it will open a new compose window with the contents of your current task list. This works in all views (my order, sort by date, completed), so to email your mom to explain why you’ve been so busy and haven’t been able to return her calls, just choose “View completed tasks” from the Actions menu, then “Email task list” and send away. (Note: this may not be very convincing if you haven’t actually checked anything off your list recently.)

If you want to let us know how Tasks is working for you, we’re now available on Twitter at http://twitter.com/googletasks. Like most Google accounts on Twitter, we won’t be able to respond to every question or feature request, but sometimes you might get lucky and we’ll have an answer for you. Oh and @sayanghosh, today is your lucky day.

Ever since we launched Google Calendar, people in our forum have been pretty vocal about a missing piece — an integrated task list. “To-do would be tooo-rific,” “I really, really, really need to use a to-do list,” and my favorite: “I’ll join your team to help you get it done!” The rumble turned into a roar a few months ago when we launched Tasks in Gmail Labs. Now we’ve integrated Tasks into Google Calendar as well.

To get started, open Calendar and click on the “Tasks” link on the left hand side. You’ll see the familiar task list you’re used to using in Gmail, with some Calendar-specific additions:

• Tasks that have due dates will automatically appear on your calendar. To create a task with a due date in Calendar, click on an empty space in month view or the all-day section of week view, and be sure select the “Task” option.



• To attach a due date to an existing task, click the right-arrow from within the task list, and then click on the calendar icon.
• You can modify a task’s due date by dragging it to a different date, just as you would with a regular calendar event.
• To mark a task completed from within Calendar, just click on the task’s checkbox. (Isn’t that satisfying, overachievers?)
• To keep track of due dates before they arrive, there’s a nifty new “Sort by due date” feature available in the Actions menu at the bottom of your task list. While sorting by due date, you can reschedule a task by clicking on it in your list, then pressing control and the up or down arrow key.

While working to help bring this feature to you, I used it to keep track of my own tasks. Now I can finally check off the last one in that list: “write blog post.” Phew.
